> KafkaIO reader might stop reading from Kafka without any explicit error message if KafkaConsumer
throws a runtime exception while polling for messages. One of the Dataflow customers encountered
this issue (see [user@ thread|[https://lists.apache.org/thread.html/c0cf8f45f567a0623592e2d8340f5288e3e774b59bca985aec410a81@%3Cuser.beam.apache.org%3E])]
> 'consumerPollThread()' in KafkaIO deliberately avoided catching runtime exceptions. It
shoud handle it.. stuff happens at runtime. 
> It should result in 'IOException' from start()/advance(). The runners will handle properly
reporting and closing the readers.
